hi all...am trying to generate sinusoidal pulse width modulation using arduino-simulink for my inverter board...I simulated the SPWM logic in simulink, then installed the required support package for arduino-simulink...but i am facing some problems...I started from basic...like linking arduino and PWM block as shown belowhttps://www.physicsforums.com/file:///C:\Users\ccbzak\AppData\Local\Temp\msohtmlclip1\01\clip_image001.png I checked the output of Arduino pin11 from CRO and it was working fine….
Now I used this blocks to generate spwm…

When I checked the output from CRO…..it was distorted…literally I didn’t get any SPWM wave…
Help me out with problem…
My Simulink configurations are
Solver: fixed step size
Step size:1e-5
Triangle wave frequency is 8KHz and sine wave is 50Hz…
